Definition of Unearned Revenue in Accounting. Unearned revenue is the same thing as deferred revenue. In accounting, unearned revenue is a liability. It is a liability because even though a company has received payment from the customer, the money is potentially refundable and thus not yet recognized as revenue.
The accounting equation identifies three major classifications of business transactions. These items include assets, liabilities and owner's equity. Unearned revenue is a liability, as a company receives funds for goods not yet delivered or services not yet performed. Proper accounting is necessary to ensure the company does not mislead stakeholders in this information.
